It’s been 25 years since the National Weather Service packed up and moved to Shelby County from the Birmingham International Airport.

The weather service is marking that milestone on Saturday with an open house at its office at the Shelby County Airport in Calera.

It’s free and open to the public. You’ll get a look inside the operations area and get a chance to meet weather service meteorologists.

“It’s a chance for us to open our doors and anyone can come visit us and see what we do,” said meteorologist Jessica Winton.

Area first responders are also planning to be there as well as TV meteorologists and their chase vehicles.

According to the weather service there will be activities for the kids, including trick or treating, and a chance to help launch a weather balloon at noon.

The open house will be from 10 a.m. until 3 p.m. on Saturday, Oct. 27, at the office, which is located at the Shelby County Airport at 465 Weathervane Road in Calera (the ZIP is 35040).

The Birmingham weather service office covers 39 counties in central Alabama. There is also a weather service office for north Alabama in Huntsville, one for southwest Alabama in Mobile, and the southeast corner of the state is covered by the weather service office in Tallahassee, Fla.
